The number of Internet domain names grew by nearly 3.5 million in the final three months of 2010 according to Verisign's Domain Name Industry Brief released today.

The report says the total number of registered domains increased by 12.1 million names or 6.3 percent during 2010 bringing the number of registered domain names across all Top Level Domains (TLDs) to 205.3 million.

The two most popular top level domains are .com and .net which finished the year with a combined base of approximately 105.2 million names. New .com and .net registrations totaled 7.6 million during the fourth quarter, an increase of 4 percent from a year ago.

Of the over one hundred million registered of .com and .net domains, Verisign estimates that 88 percent of .com and .net domain names resolve to a website, meaning that an end-user visiting that domain name would find a website. The report says that about three quarters of those that resolve to a website were multi-page websites with about a quarter being one page websites which include under construction, brochure-ware, parked pages or online advertising revenue generating parked pages.

The base of Country Code Top Level Domains (ccTLDs) was 80.1 million domain names, a 0.3 percent increase from a year ago. There are more than 240 ccTLD extensions globally, with the top 10 ccTLDs comprising 61 percent of all registrations

Poland and Australia also joined the Russian federation and the United States as top 20 ccTLDs exceeding 20 percent year-over-year growth. Among the 20 largest ccTLDs, Poland, Australia, Canada and Switzerland exceeded 4 percent quarter over quarter growth. Last quarter, four of the top 20 met the same threshold.

Verisign's average daily Domain Name System (DNS) query load during fourth quarter 2010 was 61 billion, with a peak of 72 billion. Compared to the same timeframe in 2009, the daily query average and the peak both grew by 17 percent.
